Businesses transferring data are often tempted to place files on USB devices for ease of transport, but this could be opening up businesses to considerable risk of data loss or security breaches.
Karsten Nohl, chief scientist at SR Labs in Germany, told TG Daily that malicious software can easily be uploaded to these devices and when they are connected to business networks, the malware can wreak havoc on internal systems, resulting in the need for extensive data recovery measures.
The expert demonstrated the frailty of many business networks to this type of threat at the Black Hat Conference in the US last year, in which he was able to gain remote access to a computer simply by uploading a virus via a USB to a machine connected to its network.
“Now all of your USB devices are infected. It becomes self-propagating and extremely persistent,” Mr Nohl stated.
As a result, companies need to be increasingly aware of this potential danger and take steps to limit the use of USBs.
